ive had Nippon shafts for a few years now and love them. I had these shafts in my recent irons and were great, but I tested the latest Modus3 105 shafts and bought them from Tourspec.com and have got them in my new irons. They are 106.5g compared to the 120's at 114g and are fantastic. I'm getting an extra 6mph more with the 105 to the 120 and I just suit a lighter weighted shaft.
I wont use any other iron shaft but Nippon.
